Blisters When You Walk Higher Miles. Walking 10 miles (over 3 hours), even if you are used to walking for six miles, is more of a challenge. You can do it, but most people are likely to develop blisters in new places. Shoes and gear that worked fine for two hours may not be ideal for four hours.
How the Aurora Borealis occur. The Northern Lights are caused by the interaction of the solar wind - a stream of charged particles escaping the Sun - and our planet's magnetic field and atmosphere.
Your best chance to see the northern lights is during the cold, clear winter nights between September and April. The prime time to see them in all their glory in usually after midnight. Be spontaneous, brave the cold, and embrace a late night adventure to see the stunning natural phenomena Alaska is known for.
